We added the `@enableTreatRefLikeIdentifiersAsRefs` feature a while back but never enabled it. Since then we've continued to see examples that motivate this mode, so here we're fixing it up to prepare to enable by default. It now works as follows:
* If we find a property load or property store where both a) the object's name is ref-like (`ref` or `-Ref`) and b) the property is `current`, we infer the object itself as a ref and the value of the property as a ref value. Originally the feature only detected property loads, not stores.
* Inferred refs are not considered stable (this is a change from the original implementation). The only way to get a stable ref is by calling `useRef()`. We've seen issues with assuming refs are stable.
With this change, cases like the following now correctly error:
```js
function Foo(props) {
const fooRef = props.fooRef;
fooRef.current = true;
^^^^^^^^^^^^^^ cannot modify ref in render
}
```
babel-plugin-react-compiler
React Compiler is a compiler that optimizes React applications, ensuring that only the minimal parts of components and hooks will re-render when state changes. The compiler also validates that components and hooks follow the Rules of React.
This package contains the React Compiler Babel plugin use in projects that make use of Babel. You can find instructions for using this plugin here: https://react.dev/learn/react-compiler
